onion - like other posts I am very curious how you hear this information!!!!! Are they really adding a 4th flight????? I would have though that, considering it's not on sale, and to the commercial sensitivity over changes that happen, that the only people who would know would be bmi themselves, and the airport!!! And surely no-one in them companies would give away company secrets!!!!!
I've always wondered where these start.
However, a 4th does make a bit of sense, ignoring the first flight (which I thought would have been good for business people???), consdeiring that NCL has 7 a day to LHR and 5 to LGW with BA , not counting the easy flights to STN!!! (correct me if I'm wrong on those)
